The general secretary of Manchester City's official supporters' club has been left disappointed by comments from manager Pep Guardiola about stayaway fans last night.
Guardiola sought to rally the support after 17,000 fans snubbed their Champions League victory over RB Leipzig.
"It did surprise me," Parker told the PA news agency. "I'm not sure what that's got to do with him.
"He doesn't understand the difficulties that some people might have getting to a game at the Etihad on a Wednesday evening at 8pm.
"He's absolutely the best coach in the world but, in the nicest possible way, I think maybe he should stick to that.
"It just takes the edge off what was a good night. People are talking more about Pep's comments than a fantastic game.
"To question the support, which is effectively what he is doing, is disappointing and uncalled for.
"It does also play into the hands of supporters from other teams who want to take every opportunity to have a go at City for what they think are the poor attendances.
"People refer to the Etihad as the 'Emptyhad'. It's a little bit of fun by the opposition supporters but there's no justification for it.
"It's not factual. Our attendances are generally excellent."
